question about upgrading from vers 5 to 7

Post by BillG » Mon Apr 04, 2011 9:48 pm

I finally had time to install 7 on my machine. I deleted the 5 twain.dll from the project and added the 7 twain.dll. What do I do about the controls on my form? When I compile I get the following error.

Error 1 The type or namespace name 'VSTwain' does not exist in the namespace 'Vintasoft.Twain' (are you missing an assembly reference?) C:\Software Development\vs2010\LaborWare\LaborWare_WinForms\MemberRelatedDocsListForm.Designer.cs 247 33 LaborWare_WinForms

private Vintasoft.Twain.VSTwain vsTwain1;

Do I have to bring a new control into the project. The instructions were unclear on that. Where is the control?

The point is that there were plenty of changes in SDK architecture since version 5.

So the namespace "VSTwain" does not exist anymore in v7.

VintaSoft created the Upgrading Guide specially to make the upgrading process easier.

Please refer to SDK documentation (can be found in /Help folder):
"Programming > Changes history"
